    Abstract: A dialysis machine is disclosed that incorporates a water treatment module, a dialysate preparation module having a dialysate circuit, and an extracorporeal circuit including a dialyzer and arterial and venous blood lines that connect to the patient. The machine accomplishes on-line disinfection of all the fluid circuits of the machine, including the water treatment module, the dialysate preparation module and extracorporeal circuit, the arterial and venous lines, and the dialyzer, by circulating water heated to a high level disinfection temperature (e.g., 80 degrees C.) through the fluid passages of the machine for a sufficient time (such as an hour) to achieve high level disinfection. After the dialysis session is ended, the patient connects the arterial and venous lines to ports in a disinfection manifold that places the arterial and venous lines into fluid communication with the heated water. Thereafter, the machine is ready to disinfect the fluid circuits including the extracorporeal circuit.

  • Patent number: 4988525
    Abstract: For selective removal of volatile substances from liquids, the initial liquid is fed to a crosscurrent diaphragm separation device (2), in which the permeate consisting of water and volatile substances is separated by increased transdiaphragm pressure and concentration difference. Then, the permeate is fed into a further liquid-volatile separation device (8), in which the alcohol is distilled out. The permeate now only consisting of water, salts, acids and extracts is then fed back into the crosscurrent diaphragm separation device (2), where it flows through the permeate side in countercurrent to the flow of the retenate. Excess permeate can be introduced into the dealcoholized initial liquid. By the process according to the invention the economic efficiency of the unit and the quality of the end product are significantly improved.
